Gugus pulau Togean memiliki potensi sumberdaya perairan yang dimanfaatkan untuk kegiatan wisata bahari. Peningkatan kunjungan turis pada periode tertentu menyebabkan aktivitas wisata dan kegiatan terkait meningkat, sehingga berpengaruh terhadap penurunan kualitas perairan dan obyek wisata. Penelitian ini bertujuan untuk mengkaji keterkaitan antara musim kunjungan turis dalam setahun dengan perubahan yang terjadi pada beberapa parameter kualitas perairan laut di sekitar kawasan obyek wisata. Metode analisis yang digunakan adalah PCA (Principal Component Analysis) dan analisis IPL (Indeks Pencemaran lingkungan). Hasil penelitian menunjukkan bahwa peningkatan kunjungan turis menyebabkan peningkatan nilai BOD5, COD, dan NH3 serta penurunan nilai DO di perairan. Nilai korelasi keempat parameter tersebut lebih tinggi pada bulan Nopember dibanding Juli, dan merupakan komponen parameter pembentuk sumbu utama pertama di kedua musim. Peningkatan nilai kekeruhan, penurunan salinitas dan suhu pada bulan Nopember dibanding bulan Juli karena terkait dengan musim penghujan dan gelombang yang tinggi. Indeks pencemaran lingkungan perairan meningkat 21,05% selama musim puncak kunjungan turis, namun secara umum perairan gugus Pulau Togean masih dalam kategori belum tercemar. Kata kunci : kualitas perairan laut, aktivitas wisata, Gugus Pulau Togean Marine resources of Togean Islands have been used for tourism activity. The increasing number of tourist in certain period every year has lead to increasing of tourism activity and its related activity. This condition probably effects sea water and habitat qualities. This research aim to studied correlation between tourist season in one year and the change of marine water quality parameters in tourism area. The data were analyzed using PCA (Principal Component Analysis) and EPI(environmental pollution index). The result showed that BOD5, COD, and NH3 increased while DO decrease during the peak season of tourism activity. The correlation value of those four parameters was relatively higher in November than in July. Those parameters were the component that forms the main axis in both seasons. The increasing of turbidity and decreasing of salinity and temperature in November rather than in July were correlated with rainy season and high wave. Water pollution index increasing during peak season of tourism activity, but in general, marine water quality of Togean Islands can be categorized as good (not yet polluted) based on water pollution index. Key words: sea water quality, tourism activity, Islands Togean

Coastal areas have an important role in economic development. Development activities carried out on land and at sea can put pressure on ecosystems in coastal areas, thereby reducing the quality of the ecosystem services provided. Understanding the impact of development on ecosystems in coastal areas requires an economic assessment in order to provide input in the formulation of sustainable development policies. This article aims to estimate the economic value of ecosystems in coastal areas based on spatial. The economic valuation method used is the benefit transfer method, the travel cost method, and the replacement cost method. Mapping the economic value of coastal ecosystems based on spatial using Geographic Information System (GIS). The economic value of the coastal area is divided into 3 zones, namely zone 1, in the northern part of the Bontang River estuary, amounting to IDR 21,85 trillion/year; zone 2, between the Bontang River estuary and the Blusu River estuary amounting to IDR 48,20 trillion/year; and zone 3, in the southern part of the Blusu River estuary, amounting to IDR 45,67 trillion/year. The economic value of ecosystems in coastal areas based on the spatial obtained can explain the value lost due to ecosystem disturbances more specifically and clearly in certain zones.

Resilience is a concept that cannot be generalized. This is because in analyzing resilience, the parameters that have been used for the resilience analysis is depend on the resilience context itself. It is important to establish which parameters are most important to be used for analyzing resilience of fishermen related to fisheries resources. Fishers' are the most vulnerable community and have a high depencency on natural resources. It is necessary to analyze of fishers' resiliences. The resilient fishing communities can increase their capacity to cope on socio-economic change. The purpose of this study is to determine the parameters that can be used to analyze resilience of the fishermen in small islands. The study was conducted from February to April 2018. The method used in this studyis expert judgment. Based on previous studies to analyze resilience used 6 dimensions, namely: social (21 parameters), economic (26 parameters), institutional (13 parameters), infrastructure (12 parameters), resources (9 parameters), and potential disaster (2 parameters), the total parameters are 83 parameters. Based on the result, 83 parameters were being indexing and only 53 parameters having values above 3,50 are used to analyze resilience assessment. The parameters that have the highest index in each dimension are the level of poverty (social dimension), number of livelihood (economic dimension), government role (institutional dimension), and fish catch (resource dimension).The selected parameters are used to analyze the fisher’s resilience in Karimunjawa islands.
